By Imnokuffar-If it is a Muslim who kills other Muslims then they cannot be Muslims, so they must be Jews, Infidels or Martians. Or so the logic goes.
Try following this story and you will see what I mean.

Egypt’s army vowed last Monday to “avenge” the killing of 16 troops by gunmen near the Israeli border, as President Mohamed Morsi ordered security forces to take full control of the Sinai Peninsula.

In last Sunday’s attack, 35 gunmen in Bedouin clothing opened fire on the troops before crossing into the Jewish state in an armoured vehicle, Egyptian officials said.

Israel said five gunmen were killed on its side.
The 1979 peace treaty between Egypt and Israel, under which Israel withdrew from the Sinai which it had occupied in the 1967 Middle East war, set strict limits on Egyptian troop numbers in the peninsula.

But Israel has complained of growing lawlessness on its southern border since the overthrow of veteran president Hosni Mubarak last year and called for action by Cairo.
“We swear in the name of God to avenge them,” the Egyptian army said. “Egyptians will not have to wait long before they see a reaction to this attack by terrorists.”

“Anyone liaising with these groups that have attacked our troops in the Sinai in recent months will pay dearly, be it inside Egypt or abroad,” it added.

Now the Muslim Brotherhood puts its oar in.

Israel dismisses accusation of involvement

Now both Iran and Egypt officially blame Israel for the attack on the border point in Egypt yesterday.

JERUSALEM (Reuters) – Israel on Monday dismissed a claim by Egypt’s Muslim Brotherhood that it was in any way involved in a deadly attack on a police station in Sinai a day earlier in which 16 policemen were killed. “Even the person who says this when he looks at himself in the mirror does not believe the nonsense he is uttering,” Foreign Ministry spokesman Yigal Palmor said.
Egyptian Muslim Brotherhood declares the ‘Islamist’ attackers as ‘infidels’

RAFAH, Egypt (Reuters) – Egypt branded Islamist gunmen who killed 16 police near the Israeli border as “infidels” and promised on Monday to launch a crackdown following the massacre that has strained Cairo’s ties with both Israel and Palestinians.
An Egyptian official said jihadist militants crossed into Egypt from the Gaza Strip before attacking the border station on Sunday. They then stole two vehicles and headed to nearby Israel, where they were eventually killed by Israeli fire.
Israeli Defence Minister Ehud Barak said on Monday that up to eight assailants died in the attack, adding that he hoped the incident would serve as a “wake-up call” to Egypt, accused by Israel of having lost control of the desert Sinai Peninsula.

So let me get this straight.

Israel got 35 men to cross over from the Gaza Strip to massacre 16 Egyptian Police officers or as many as they could find.

The Israelis told them to steal two armoured vehicles (some accounts say three and one blew up with the terrorists still in it) and head back to Israel to massacre Israelis.

However, then the conniving Jews shot 8 of them dead to cover their nefarious tracks and avoid paying them. The Egyptians are convinced that this was the work of either the Israelis or Palestinians and the Muslim Brotherhood thinks it was the work of ‘Infidels’ which is a catch all phrase for non-Muslims.

It is a well known fact that there are no terrorists in the Gaza strip so by process of elimination that leaves only the Jews or the undefined ‘Infidels’ and as Muslims cannot be Infidels then it could not be Muslims who did this.
I have another theory. It was the Martians and it was in retaliation for the recent invasion of their territory by the Curiosity.

Yup, now that makes sense.
